ANTRIH,-OF GLOUCESTER, NEW JERSEY, ASSIGNOB T0 ROBERTS MANDER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLV'ANIA Gas man Application led October 80, 1931. Serial No. 570,019.

My invention relates to certain improvements in the arrangement of the burners and gas pipes leading thereto of the oven of a ga range.

One object of my invention is to locate the piping within the casing of the oven or ovens and to provide handles for the gas valves, which are located at a convenient point, preferably in alignment with the other valves of the gas range.

Another object of the invention is to so construct the range that the gas burner mixing chambers are located within the casing of the range but are accessible from the front of the range, leaving the sides and back clear so that the range can be permanently located against a wall at either side.

Another object-of the invention is to provide removable cap plates enclosing the mixing chambers but which can be readily removed when it is necessary to adjust the air openings of the mixing chambers, giving a neat appearance to the range.

A further object of the invention is to locate the mixing chambers or Bunsen burners between the inner and outer walls of the oven, the air adjustments being accessible from the outside of the oven.

Fig. 6 is a skeleton perspective view showing the burners and piping of the range shown in Fig. 5; and

Fig. 7 is a detached perspective view of one of the detachable plates.

- Referring in the first place to Figs. 1 to 4, inclusive, the range a has a top plate b and an oven structure c under the top plate. The gas manifold is at the front of the range and enclosed within a casing d. The handles e for the several gas cocks of the top plate burners are on the outer side of the casing as shown in Fig. 1. At the extreme right of the series of handles is the handle 25, controlling the flow of gas to the baking and broiling burners 14 and 15 Within the oven. The oven has in the present instance inner plates 2-2a and outer plates 3-3a spaced apart, and-in this space is heat non-conducting material 9. The inner side plate 2a is detachable. 4 4 are rack plates for the slides of the oven and 5 is a bottom plate of the oven. 6 is the bottom plate of the oven structure. 7 is the inner 65 top plate of the oven and spaced from this is the outer plate 8 and in this space is heat nonconducting material 9a. At the lower right# hand corner of the oven structure in the present instance is a compartment 10 formed by a 'fo detachable plate 11, the bottom plate 6 and side plate 3, and at theupper end of the oven structure is a compartment 12 formed by the detachable plate 13 and the top plate 8 and side plate 3. The two detachable plates are held in place by the inner detachable oven plate 2. i

14 is the baking burner, which is located under the bottom plate 5 of the oven proper and 15 is the broiling burner, located in the upper part of the oven.- 16 is the mixing chamber of the burner 14, the burner being connected thereto by a pipe 17, and 18 v is the gas pipe which extends into the mixing chamber. The mixing chamber is of the ordinary type used in gas ranges and has suitable air openings. l 19 is a mixing chamber connected by a pipe 20 to the broiler burner 15, and 21 is a gas pipe which extends into the mixing chamber 19. The gas pipe 21 is connected to a pipe 22, Fig. 3, which is connected in turn to the valve casing 23, and 24 is a pipe connecting the gas pipe 18 of the lower mixing chamber with the valve casing 23. 23a is a valve stem having a suitable handle 25. The valve casing is connected to. the manifold `pipe 26, which usually extends across the front of the range. j

The valve 23 is a double valve of ordinary construction, so that when the handle is turned in one directionv the gas is admitted to the lower oven burner and is cut off from the upper broiling burner and when the valve is turned in the opposite direction the gas is admitted to the broiling burner 15 and cut off from the lower baking burner 14.

The pipe 24 is located in the space between the detachable side plate 2 and the outer side plate 3, so that the piping and manifolds are all located within the oven structure and are not exposed to view, but access can be had to the pipe 24 and the mixing chambers 16 and 19 by.l removing the inner side plate 2 and the detachable enclosing plates 11 and 13.

In the front plate 27 of the range are openings in which arelocated detachable perforated cap Aplates 28. These cap plates are directly in line' with tbe ends of the mixing chambers, so as to allow air to enter the mixingl chambers from the outside. The cap plates can be removed when it isV necessary tol regulate the air lopenings of the mixing chambers.

In `referring to Fig. 1, it will be seen that the entire piping between the mixing chambers'and the baking burner and the broiling burner are located within the oven, and are entirely enclosed within the casing. making a very neat appearance and preventing tampering with the parts.

Figs. 5 and 6 illust-rate a modification, in

` which the invention is applied to a gas range in which there is a lower oven C1 and an upper oven C2, the lower oven having a single baking burner at the bottom thereof, and the upper oven having a baking burner at the bottom and broiling burner at the top.

Referring to the skeleton perspective view,

lFig. 6, 14a. and 15a are the two burners in the upper oven C2, Fig. 1, and 3() is the baking burner located in the lower portion of the lower oven C1,Fig. 5. The fiow of gas to the burnersl 14a and 15a is controlled by a single valve in the valve casing 23a, and the valve is manipulated by a handle 25a. One pipe 22a leads to the mixing chamber 19a of the burner 15a, While the pipe `24ML leads to the mixing chamber 16a of the burner 14a. The

' valve casing 23a is connected to the manifold- 26a to which the other gas valves of the stove are attached.

32 'is the gas controlling valve casing, which is connected by a pipe 33 to the manifold 26a and in this casing is a valve 34 having a han- Vdle 35 which is located outside of the range as shown in Fig. 5. The valve casing 32 is connected by a pipe 36 to a thermostatic control device 37 of any standard type and this device is connected to the gas pipe 38 which extends into the mixing chamber 39 which is connected to the burner 30 of the lower oven 31.

'Opposite the three mixing chambers are openings in which are removable perforated cap plates 28a. These cap plates are directlyin line with the ends of the mixing chambers to allow -air to enter the mixing chambers from the outside and to allow access to the mixing chambers.

I claim:

1. The combination in a gas range, of an oven having an inner and outer casing; a baking burner in the lower portion of the oven; a broiling burner in the upper portion of the oven; and a controlling valve controlling the iiow of gas to the said burners through their mixing chambers, said mixing chambers being located in compartments formed by the inner and outer plates of the oven, the inner plates forming the compartments, being removable through the oven.

2. The combination in a gas range, of an a baking burner in the lower portion of the oven; a boiling burner in the upper portion of the oven; a controlling valve controlling the iiow of gas to the said burners; a mixing chamber for each burner, said mixing chambers being located in the upper and lower portions'of the oven structure and at one side thereof, the inner removable plates at upper and lower corners of the oven enclosing the mixing chambers; and an inner casing of the oven removably holding the enclosing plates in position.

3. The combination in a gas range, of an oven having an inner and an outer casing and a compartment in one corner of the oven for the mixing chamber of a burner; and a detachable plate forming a part of the enclosing wall of the compartment, said plate being removable through the oven.

4. The combination in a gas range, of an oven having an inner and an outer casing for the oven of the range; a detachable plate located in one corner of the oven; a burner within: the oven; and a mixing chamber located in the compartment formed by the detachable plate, said plate having a slot therein for the pipe connecting the burner with the mixing chamber, said plate being removable through the oven so that access may be had to the mixing chamber.
